ALBERT OLOF MELCHEB. LFGREN, OF STOCKHOLM, SWEDEN.

STARTING-VAPORIZER.

Application filed August 8, 1912.

To all whom t may concern Be it known that I, ALBERT OLOF MELCHER LFGREN, a subject of the Kink of Sweden, residing at Sturegatan 15, Stockholm, in the Kingdom of Sweden, have invented certain new and useful 1improvements in Starting- Vaporizers, of which the following is a specification.

rThis invention relates to apparatus for initiating vaporization of petroleum or similar fuel in petroleum stoves, incandescent lamps or the like. In such apparatus it is common to supply a small vaporizer in addition to the main vaporizer and to introduce the petroleum from the petroleum container into said small vaporizer, and to initiate vaporization therein so as to establish a flame which heats the main vaporizer.

The present invention refers to certain arrangements in connection with vaporizing apparatus of this kind and is shown in a constructional form on the accompanying drawing. i

On this drawing Figure 1 is an elevation partly in vertical section, of the vaporizing apparatus. Fig. 2 is a plan of the same, and Figs. 3 and 4 show parts of the additional vaporizer on an enlargedscale. Figs. 5 and 6 show a detail, namely, the match holder in side elevation and plan respectively. Fig. 7 is a side elevation at right angles to the side elevation, Fig. 5. Fig. 8 shows a modified construction.

1 indicates the petroleum container', and 2 the usual vaporizing apparatus with its nozzle 3. As usual the vaporizing apparatus is connected with the petroleum container 1 by means of a pipe 4, and comprises two U-shaped pipes 5, which in the constructional form illustrated, are connected with one another at their upper part by means of the annular pipe 7 at the upper side of the dispersing plate 6. A second smaller vaporizer is provided in addition to the main vaporizer 2. It comprises al pipe 8 with thin walls and of small diameter communicating at one end with the petroleum container 1 through the parts 19, 11 and 10 below described, and at the other end with a burner nozzle 9. The pipe S may, if desired, be of spiral form as illustrated in Fig. 8. The communication with the petroleum container 1 is established through a pipe 11 and a valve chamber 10 through which the pipe 4 also communicates with the container 1.

projecting piece 18 is provided through Specification of Letters Patent.

which passes a valve spindle 12, the valve 13 of' which closes' either the communication between the pipe 4 and the petroleum container 1, or the communication between the pipe 8 and said container. The burner nozzle 9 is directed in such a way, that a flame, burning in the burner jet 15, heats the main vaporizer 2, perferably by striking its dispersing plate 6. According to the present invention said nozzle is provided with a second burner jet 16, directed downwardly and directing a flame toward the vaporizing pipe 8, or toward the plate 19, below referred to.

When the main vaporizer 42 is to be put in operation, the communication between the same and the petroleum container 1 is closed by means of the valve 13. Then petroleum is introduced into the vaporizing pipe S from the container 1 in which the air above the petroleum level is compressed by means of the pump asis common in connection with petroleum stoves, 0r if the apparatus is used for incandescentlamps, from a petroleum container placed on an elevated level.-

A match is thereupon lighted and is placed in the holder 17 (Figs. 2, 5, 6 and V7) which is situated in such a manner that the flame of the match strikes the vaporizing pipe 8. 1n the construction shown, this holder is detachably supported in the lower part of the pipe 4 by means of bent supports 171 entering the holes 172, Fig. 1. The petroleum, contained in the pipe 8, is vaporized by the heat of the match and the petroleum vapor flowing out through two jets 15, 16 provided in the nozzle 9, is lighted by the flame of the burning match. By means of the flame burning at the jet 16, the vaporization in the pipe 8 is maintained when the flame of the match is extinguished, and the flame burningr at the jet 15 heats the main vaporizer 2, so that when the valve 13 is operated to admit petroleum into the vaporizer 2, vaporization proceeds in the same and the petroleum gas, escaping through the nozzle 3, is lighted by the flame burning at 16. rThe communication between the vaporizing pipe 8 and the petroleum container 1 is then closed by means of the valve 13.

Vith the arrangement described above, difficulties have been experienced in maintaining a regular vaporization in the auxiliary vaporizer chiefly owing to an irregular flow of fluid therethrough and to irregularities in the heating effect of the burner jet CIO which is directed toward the auxiliary vaporizer.

In order to establish a uniform admission of petroleum to the pipe 8 to the necessary small amount, so that the petroleum will be wholly vaporized and will flow out through the burner jets 15 and 16 in the form of a regular stream of vapor, the petroleum pipe of the additional vaporizer in the construction shown, is suitably reduced at one place, so that only a very small amount of petroleum can pass. Said reduction may be established in any suitable manner, say by fitting the petroleum pipe with a suitable pulverulent or granulous material or by providing a corrugated or checkered plate or ay fine wire cloth gauze or the like within the pipe. The drawing illustrates a suitable constructional form. rThe petroleum channel between the pipe 8 and the larger pipe 11 constitutes a long and broad flat chamber 'formed by folding a thin metal plate 19 in the manner illustrated in Figs. 3 and 4.

`The small pipe 8 and also the connecting pipe 20 of the pipe 11 open into said chamber and one or more pieces 21 of fine wire cloth are inserted therein. The plate 19 is cut to the form illustrated in Fig. 8, and after the insertion of the wire cloth 21 the plate is first folded on the line 22, whereupon th-e laps 23 and 24 are bent over. The plate is then firmly pressed together and soldered. 1t has been shown that in this way the necessary small flow of petroleum is obtained, which is vaporized, at first by the heat from the match and then by the fiaine in the burner opening 16, said iiame being directed toward the plate 19.

Owing to the fact that the main vaporizer is heated also when the petroleum has been introduced in the same, the thickness of the vaporizing pipes 5 and 7 need not be so great as to store an amount of heat suflicient to vaporize cold petroleum, and therefore said pipes may be made considerably thinner, when employing the additional vaporizer 8, than in vaporizers hitherto in use. This fact enables the connecting pipe between the vaporizing pipes 5 to be arranged as illustrated in the form of a pipe 7 of sheet metal fixed to the dispcrsing plate 6, whereby the construction is simplified.

The two burner jets 15, 16, are preferably in alinement with one another, an arrangement which presents considerable advantages when it is desired to clean said jets.

Having now described my invention, what 1 claim as new and desire to secure by Letters Patent is:-

1. Vaporizing apparatus for volatile combustible, comprising a main vaporizer, and an additional vaporizer having a burner nozzle provided with two oppositely directed burner jets, the first of said burner jets being directed toward the main vaporizer and the second burner jet being directed toward the additional vaporizer.

3. Vaporizing apparatus for volatile combustible, comprising a main vaporizer, and an additional vaporizer directing a flame toward the main vaporizer, and a holder for supportingV a match beneath a part of said additional vaporizer reduced in section for initiating the evaporation in said reduced part of the additional vaporizer.
